Homophones quiz, help!

[gos618]

I'm stuck on the last few of a local quiz. The quiz is based on words that sound alike, but are spelt differently. Both words are required.
For example, Question. Emblems for percussion. Ans. Symbols and Cymbals.
1. Pathways blocked through the crop.
2. Painstakingly accurate in Welsh town
3. Open the door to musician
4. An island in Sussex?.
5. Clothing to keep you warm outside.
6. Bird needs this to travel
Any help would be greatly appreciated.

Thanks Quinie, I agree you about Calibax's Petrel/Petrol, and I think your Handle/Handel is right as well!
